Answer:
5 : 10
6 : 12
7 : 14
8 : 16
9 : 18
Step-by-step explanation:
10/5=2
there is only one number in between 7 and 5
so now you have to go up 2 each time in the right collum and go up once in the left collum.
Answer:
y= 5 and -3
Step-by-step explanation:
subtract 7 from both sides to get y^2-2y-15=0
factor the equation to get (y-5)(y+3)=0
add five on both sides to get y=5 and subtract 3 on both sides to get y=-3
